Its hard to say just going by your explanation.

Sounds as though you are either taking WAY TOO long, or you have a form of target panic.

My shot sequence goes something like this.

Set bow hand, hook up release, set stance, pre-aim slightly above the spot, draw to anchor, place finger on trigger, concentrate on the spot, and thats it....the bow goes off as Im concentrating. From the start of aim to the bow going off for me is about 5-7 seconds. The whole sequence is probably like 14-16 seconds.

Hope that helps.
Thats not the only way you can do it, but thats similar to the way most successful shooters do it.
